Bono and Annie Lennox are expected to be among the mourners who will attend later today, according to reports.

The Geldof family have said the service will be held in private.

Mystery still surrounds the sudden death of Ms Geldof on April 7.

Her body was found at the home she shared with her husband and their two young sons, Astala, 23 months, and 11-month-old Phaedra, in Wrotham, Kent, after officers were called "following a report of concern for the welfare of a woman".

Former Boomtown Rats singer Geldof paid tribute to his daughter alongside his partner Jeanne Marine and Ms Geldof's sisters Fifi Trixibelle, Pixie and Tiger, saying she was the "wildest, funniest, cleverest, wittiest and the most bonkers of all of us".

Kent Police said it was being treated as a "non-suspicious, unexplained sudden death".

An inquest is not expected to be opened and adjourned by the coroner until after the results of toxicology tests are known.
